TUNNELING APPARATUS.

Specification of Letters Patent.

Patented May 18, 1903,?

.To all whom 'it may concern:

Be it known that I, HENRY JAPP, a subject of the King of Great Britain and Ireland, and a resident of the borough of Manhattan, in the city, county, and State of New York, have invented certain new and usefull Improvements in Tunneling Apparatus, of which the following is a specification. My invention relates to tunneling apparatus and particularly to apparatus for rock tunneling, the object of my invention being to rovide an improved carriage for the. dril s, etc.- r

In the accompanying drawings, Figure 1 is a side elevation of a carriage embodying my invention; Fig. 2 is a plan thereof; and Fig. 3 is an end view.

My device comprises a carriage provided with a forwardly extending arm 11, preferably of cantaliver construction as shown, and a rearwardly extending balancing arm 12 carrying counterweights 13. The arm 11 is of such length as to extend beynd the muck pile 14 and over the bench 15 and carries the horizontal drills 16 at its eX- treinity for driving the heading and behind them the vertical drills 17 for breaking down the bench. To afford a 'suitably rigid support for the drills, I mount theln adj ustab y upon thev columns 18, which for the 'Vertical .drills are swung at the top from pivoted brackets 19 while the bottom is provided with a foot block 20 with screws 21 for inak- Thecolumn for the vertical drills is suspended from slides on the string pieces of' the cantaliver arm, so that the bench drills may be moved closer to or farther from the heading drills as may be expedient, while the bench drills themselves may be laterally adjusted across their sup'- port-ing column if desired.

ln order to clear tlie'di'ills ol thc walls of the cut when the carriage is to be traveled,

the horizontal column 1X is suiveled on its l'or the heading drills are provided with tackle 23 attached to the block at the foot ol' each co|- l unin, by means of which the latter, being bc hoisted up'out ol the way of the dumpcars, Should the apparatus get out of order for any reason, it could be rolled back out of hinged to the brackets It), may be swung up -to clear the bench llooi'.

When it is desired to fire a blast the drills and tlieirsupporting coluins, instead of bring dismantled and carried back out oll danger, are merely swung upon the cantaliver arni i i l safe distance. After the blast the carriageis again run forward, the columns loweredl to position and the drilling operations can begin labor heretofore lost.

To facilitate the moving of thec'arriage, it

which is carried 1n the direction which it is desired to move the carriage, fastened to a convenient projection, for instance, adrill stuck in a crevice in the rock, and the winch set in operation. A roofing 25 3) may be placed over the carriage and cantaliver arm, or over the latter alone, to protect tlfe workman against drip' or accidental falls from the unfinished roof of the cut'.V I.

My carriage may also be provided with a conveying apparatus for removing the muck and delivering it to the cars. To this end I mount a pair. of inclined slides 25'* beneath the carriage proper, the lower ends ofwlch reach to the foot ofthe muck pile. A scoop or pair of scoops 26 is pulled, on the loadingtravcl, by a heavy rope 27 passing around a pulley 28 to the smaller cylinder of thewinoh, anden the return stroke by alighteifropet) passing around the }p ulley0-to thelargerA cylinder of the wine 1. At the forward end of thecarriage the scoops are lifted by the arm ltabove the bench so that they can as` sist in removingthe muck brokendown by the heading drills. A handle 81 is provided for the scoop by which the latter maybe guided into the muck pile when filling. After the 4scoop is filled, it slides down the muck pile to the foot of the incline up which it is pulled by the winch, fin-ally assing along the horizontal section 32 to t 1e point of discharge, when it emptiesinto a car.

ln order to provide against interruption of work in case of a break down of the device, the carriage is iliade of sufficient width to s )an the tracks of the dump cars and the slides 25 are hinged at their upper ends and provided with tackle 2&3 by which they may the way, the slides lifted and the tunneling4 work progress without serious interruption.

. A considcrabli-i. saving is also made, in case the drills are operated pneumatically, by car- (shown in dotted lines, 7.0

back to a l rying the compressed air through metal tubstructure shown.

l claim as my inevntion:

1. Apparatus for bench tunneling, com-.

prising a traveling frame and a forwardly cxtending arm therefor, carrying horizontal drills for making a heading in the upper portion of the tunnel and Vertical drills in the rear of the horizontal drills for breaking down the bench, substantially as described.

2. Apparatus for bench tunneling, comprising a traveling frame and a forwardly extending arm therefor carrying horizontal drills for making a `heading in the upper portion of the tunnel and vertical drills in the rear of the horizontal drills for breaking down -the bench, in combination with a conveyer apparatus carried in part by said forwardly extending arm, the eonveyer proper being brought above the level of the .bench to remove the muck broken down by the heading drills, substantially as described.

3. Apparatusy for bench tunneling, comprising a traveling frame and a forwardly extending arm therefor adapted to carry the drills above the bench, in combination with a drill support movably mounted on said arm and means for swinging said drill support clear of the tunnel Walls when the carriage is to be traveled, substantially as described.

4. Apparatus for bench tunneling, comprising a traveling frame and a forwardly extendin arm therefor adapted to carry the drills a ove the bench, in combination With a vertical drill support `and means for swinging the saine up to clear the bench floor when the carriage is to be traveled, substantially as described.

5. Apparatus for bench tunneling7 comprising a traveling frame and a forwardly extending arm therefor adapted vto carry the drills above the bench, in combination With a horizontal transversedrill su pport and means for swinging the sam on a vertical axis so as to clear the walls oft "le tunnel when the carriage is to be travelled, substantially as de? scribed.

6. Apparatus forlll'cnch tunneling, conn prising a traveling frallihe and a forwardly extending arm therefor, carrying horizontal drills for making a hel, l' 5g in the upper portion of the tunnel anllln'tnfical drills in the rear of the hcrizonltill lh-ills for breaking down the bench, in crilmbination with a rigid fluid conduit mountet, on said carriage and extending up said arn' to the drills and ilcxiblyr connected at one lid-,to the drills and at the other to'a mainsupply pipe, substantially as described. i i

In testilno ily \`vhercdll `l have signed my name to this Ikpecgiilication, in the presence of two subscribil'tg witnessed. 'h
